The invention relates to locomotives having boiler-supporting frame or bed side members, provided with a plurality of journal box openings, and more-particularly to a sectional frame or bed having a front section-or portion formed as anintegral structure.

A locomotive frame or bed of integral formation possesses a high lClBglBGOf strength, rigidity and durability in proportion to its in weight, with an attendant material increase in the factor of safety, and effects a'substantial economy in maintenance cost.

Heretofore, when an integral frame'or bed has been employed in the above type of locomotive, it has been made to extend throughout at least the entire length of the side members including the ournal box openings, or has been made to include only aportionthereto the present invention, it has been discovered that the principal advantages of a locomotive integral frame or bed may be attained, if that portion only of the frame or bed he made as an integral structure that includes the seetion wherein all or substantially all of the working of the side framemembers, cross ties, and associated parts take .place,which has been found to be substantially comprised in that part of the frame or bed extending from the main axle forward, and if this is formed in a rigid one piece casting without f any bolts orother fastening, there is no dificulty whatever in maintaining a built-up construction back of the main axle.

plates making the sidemembers of a locomotive frame or bed in sections, by dividing them at a suitable point to the-rear of the main journal box openings, and formingthe front portions and cross members as an integral structure, The most suitable pointof division has been found to be to the rear of the main journal box openings, between these v M The present invention therefore, contem-,

the mam ournal openings. An integral j partial "frame is thus provided which includes, as an integral casting unit, those parts whereinsubstantially all of the undesirable working of parts usually take place. Such a structure is found to have substantially all 58 the advantagesof an all integral bed or frame. There is no material difference in maintenance, while on the other hand, there ,is a material saving in the cost of manufacture. Furthermore the integral portion, in 60 the presentimproved construction, being relat vely small, is more easily machined and more readily applied. Moreover it is more readily replaced and with less cost if occasion requires, and likewise the portions to the rear 05 .may be replaced without in any Way disturb- ,ing or necessitating the replacement of the forward integral section. of in advance of the maindrive. With regard While it has been stated that the side members are preferably divided between the main journal opening and the journal opening tothe rear thereof,

it is obvious that the integral portion may be extended somewhat rearwardly without departing from the spirit of theinvention, for, while the greatest advantage is believed to be in the provisionof an integral frame portion 7 made nolonger than is necessary to attain the desired ends, obviously much of the benefits will be attained even though the integral portion be somewhat longer. 7 30 .Theinvention as thus set forth, being borne in mind, it further contemplates the addition,

as part of the integral structure, of one or more of the features usually associated with the forward portion of a locomotive bed, as, 35

for instance, the bumper, or bumper seat, the

saddle, cylinders, and boiler guide bearing seat. Furthermore, the rear portion of the frame, which is suitably formed for rigid fastening to the forward integral portion, may also be made integral, or may be ofcomposite structure, ormay be a combination of both, and may also be made integrally with one or more of the features usually associated with this portion of the bed.

The improvement claimed is hereinafter fully set forth.

In the'accompanying drawings Figure Iris a diagrammatic side view of a locomotive embodying, the invention, Fig. 2, a side view enlarged of a fragment of the frame or bed sections of Fig. 1 including the joint, Fig. 3, a transverse sectlon of the jolnt taken on the hue 3-3 of Fig. 4, Fig. 4, a View in perspective of an entire locomotive frame or bed comprised of two integral sections rigidly connected with the cylinders and various other parts integrally formed 011 the front section or unit, Fig. 5, a fragmental View similar to 1, showing the cylinders attached, Fig. 6, a view similar to Fig. 5, the forward end of the front unit being modified to provide for the attachment of the cylinders and saddle,

Fig. 7, a view similar to Fig. 4, showin a,

' supported on a frame or bed B, in any usual or preferred manner. At the forward endof the locomotive is the usual bumper C, and the cylinder saddle, D, from which is disposed on each side of the boiler the cylinders, E, and the attendant driving. gear denoted generally by the reference F. The locomotive is shown of a type having four pairs of "driving wheels indicated by the reference, G,

a four wheel forward truck, H, and a two wheel trailing truck, I.

Considering now thatpart of the locomotive frame or bed structure which has more directly to do with the present invention, the

forward frame unit or section, B1,'in each of the views'of the drawings is shown as formed of an integral casting preferably of steel.

The rear unit B2, is shown in most of the viewsv as an integral casting, but this unit may, with satisfactory results attendant, be

made as a built up structure, or even a combined integral and built up structure, as exemplified in Fig. 7 of the drawings.

tegral front portion B1 of the frame or bed, comprises the two side members, 10, provided with the journal box pedestals, 10a, 10?), two pair being shown, the second pair,10b, being the main pedestals for the main drive of the locomotive as clearly shown in Fig. 1. The

' side members are ofdouble wall construction,

closed about the pedestals, and at top and bottom, but have large openings, 100, between the pedestals to lighten thestrueture.

The side members are connected across their top faces by a top plate or web, 1003, which is provided with the openings, 106, to lighten the structure, and with the openings, 10), and

109, for permitting the spring hangers and spring saddles, (not shown), to respectively extend therethrough.

The forward end of the integral frame structure is extended beyond the first pair of pedestals, 10a, and at the forward ends of the extended side members is provided a bumper seat, 11, to which the bumper C is attached, or if desired the seat may be omitted and the bumper made part of the integral structure. To the rear of the bumper seat the cylinder saddle, D, a transverse vertical strengthening plate, 12, at the front of the Saddle, a substantially. horizontal transverse strengthening plate, 13, at the rear of the saddle, a guide bearer seat, 1 1, to the rear of the plate, and cylinders, E, at either side of the'saddle, all integrally formed as a unitary casting, with the integral frame section as already described.

hile the above features are described as forming part of the integral structure, it will be understood that some of these parts may be made integrally with the frame section, and others associated therewith by bolts or other fastenings as the exigencies of each case will dictate. For instance, Fig. 5', shows the forward integral structure as being formed with side members having portions. 10h, adapted for receiving the cylinders, E1, which are secured thereto by fastenings. 15. The type of locomotive shown in Fig. 5, further includes a strengthening web, 16, having an orifice, 16a, to lighten the structure. Fig.

'6 shows the forward end of the integral portion of the frame or bed, instead of being formed with an integral saddle and cylinders, as being formed with a transverse plate or web, 17, connecting the extended side members, provided with openings, 17a, to lighten the structure, and a depressed shouldered portion, 18, serving as a cylinder saddle seat, all of which are integrally formed with the pedestaled port-ion of the integral structure as a unitary casting.

The casting as shown in 1 to 7 inclusive, terminates at the rear in an end portion, 19, which forms one member of the joint connecting the two. sections of the frame. The other ortion. 20 of th, 'nt Referring particularly to F 1gs. 1' 1, the inp a e 10] 1g formed on the forward end of the rear section of the frame, which is shown in Figs. 52
